Question

Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 2}}\quad ,&{\color{blue}{ -8}})\quad
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= -2
\\ \quad \\

y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values and solve for "y"}\\
\qquad \uparrow\\
\textit{point-slope form}\)
